    foam in oil gas separators

    foam in crude oil foam is a small bubbles of gas surrounded with a thin film of oil, this phenomena reduces the separation efficiency, foam exists in the gas oil interface when separator pressure decreases, or because of the surface tension, viscosity, and some impurities, because of that, small droplets are generated, these droplets are covered with oil, this happens when gas is liberated. in general; the quick motion inside the separator will cause foaming, this foam will cover the fluid surface and prevent gas from escaping, foam also reduces gas space inside the separator, and can pass the demister and escape to the gas outlet in the form of…

    Gas–Oil Separators part. 2

      Inlet Diverters Inlet diverters are used to cause the initial bulk separation of liquid and gas. The most common type is the baffle plate diverter, which could be in the shape of a flat plate, a spherical dish, or a cone. Another type, is the centrifugal diverter; it is more efficient but more expensive. The diverter provides a means to cause a sudden and rapid change of momentum (velocity and direction) of the entering fluid stream. This, along with the difference in densities of the liquid and gas, causes fluids separation. Wave Breakers In long horizontal separators, waves may develop at the gas–liquid interface. This creates unsteady fluctuations in the liquid level and would negatively affect…
